* MPC824x: remove obsolete "PN62" boardWolfgang Denk2013-11-11-10/+0
| | | | | | | | | | | The MPC824x processors have long reached EOL, and the PN62 board has not seen any board-specific updates for more than a decade. It is now causing build issues. Instead of wasting time on things nobody is interested in any more, we rather drop this board.

* pcnet: enable the NOUFLO featurePaul Burton2013-11-09-0/+15
| | | | | | | | | | | | | | On relatively slow boards (such as the MIPS Malta with an FPGA core card) it can be extremely common for transmits to underflow - to the point where it appears they simply do not work at all. Setting the NOUFLO bit causes the ethernet controller to not begin transmission on the wire until a transmit start point is reached. Setting that transmit start point to the full packet will cause the controller to only transmit the packet once it has buffered it entirely thus preventing any transmit underflows from occuring and allowing the controller to function on slower boards.

* pcnet: add cache flushing & invalidationPaul Burton2013-11-09-0/+16
| | | | | | | | | | | Ensure that the view of memory from the CPU & the ethernet controller is coherent at the various points where they exchange data. This prevents stale data from being transmitted or received, and prevents the driver from getting stuck waiting for the ethernet controller to update descriptors when in reality it has but the old values are being read from cache.

* pcnet: s/le16_to_cpu/cpu_to_le16/ in pcnet_sendPaul Burton2013-11-09-2/+2
| | | | | | | This should cause no change to the generated code, but is semantically correct. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* pcnet: code style cleanupPaul Burton2013-11-09-125/+123
| | | | | | | | | Fix up the code to match Documentation/CodingStyle. This is mostly removing extraneous spaces. No functional change is intended. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* net: pcnet: use pci_virt_to_mem to obtain buffer addressesGabor Juhos2013-07-24-1/+1
| | | | | | | | | | | | | | The pcnet driver uses the pci_phys_to_mem function to get the memory address of the DMA buffers. This This assumes an 1:1 mapping between the PCI and physical memory which is not true on all platforms. On MIPS platform U-Boot is running within a mapped memory region, and the pci_phys_to_mem macro can't be used to obtain the memory address of the buffers.

| | | | | | | | | | | | | | | | | | Change return values of init() functions in all Ethernet drivers to conform to the following: >=0: Success <0: Failure All drivers going forward should return 0 on success. Current drivers that return 1 on success were left as-is to minimize changes.
